1. Introduction
The highly sensitive GDD IP Receiver GRx8mini is a compact unit designed for high productivity
resistivity and time-domain induced polarization (IP) surveys in mineral exploration, groundwater
exploration, geotechnical investigations and other related fields. It features high capabilities
allowing it to work in any field conditions. It can be configured for multi-pole or multi-dipole
reception. The receiver uses a handheld field PC to process data acquisition and the software can
easily be updated via internet.
Characteristics:
•Reception poles/dipoles: 8 poles/dipoles for dipole-dipole, pole-dipole or pole-pole arrays.
•Programmable windows: The GRx8mini offers twenty fully programmable windows for
higher flexibility in defining the IP decay curve.
•User modes available: Arithmetic, logarithmic, semi-logarithmic, Cole-Cole and user
defined.
•IP display: Chargeability values, Apparent Resistivity, IP decay curves and pseudosections
can be displayed in real time thanks to the TFT VGA screen. Before data acquisition, the
GRx8mini can be used as a one channel graphic display for monitoring the noise level and
checking the primary voltage waveform through a continuous display process.
•Internal memory: Capacity to store up to 64 000 readings for 8 poles/dipoles, memory
expandable to 512 000 readings on the field PC. Each reading includes the full set of
parameters characterizing measurements. Data is stored on flash type memory that does
not require any lithium battery for safeguard purposes.
•Full wave data with IP Post-Processing software: The GRx8mini records and saves the full
wave data (*.mem file). This raw data can be imported, visualized and processed using
GDD's IP Post-Processing software.

3. Receiver Components
The GRx8mini components are described in this section.
A - RS-232 connector - 9 pin serial communication port
This connector is used to connect the serial communication cable between the Allegro
2
and
the GRx8mini.
B - GPS Connector
This connector is used to connect an external GPS antenna (SMA).
C - CABLE/WIRELESS switch
This switch is used to select CABLE (RS-232) or WIRELESS (Bluetooth) communication with
the field PC. The red light indicates that the switch is in the WIRELESS position.

D - ON/OFF switch
This switch is used to turn the GRx8mini ON. The ON red light indicates that the GRx8mini is
ON.
E - FUSE
This fuse prevents damages that could be caused by a defective charger.
Replacement fuse: 5x20mm 6A 125V fast action
F - SELF-TEST terminal
This terminal is used to perform a self-test.
G - R1 and R2 terminals
In pole configuration, the reference terminals (R1 and R2) are the infinite electrodes. In
dipole configuration, the reference terminal is the first electrode in differential with the
second electrode.
H - NUMBERED terminals
These terminals are referenced to the Ref terminal (Ref is infinity in pole configuration). In
dipole configuration, the numbered terminals are differential terminals.
I - CHARGER/EXT. BATTERY connector
This connector is used to charge the receiver s batteries. It can also be used to connect an
external battery pack provided by GDD (optional). The CHARGE red light on the top of the
receiver indicates that the internal batteries are charging. The light turns off when the
batteries are fully charged.

J - Input signal connector
This connector is used to connect the wires coming from the electrodes to the receiver
channels to keep the Pelican case closed while taking the readings. An optional cable mount
connector (14 pos.) can be purchased and used with the instrument.
K - RS-232 external Connector
This connector is used to connect the rugged serial communication cable (Amphenol
connector), which allows communication between the Allegro
2
and the GRx8mini receiver.
